Abstract
An improved metal coated abrasive is prepared with a controlled, rough textured surface, which surface has improved adherence to resinous materials when said coated abrasives are incorporated into resin bonded tools. Disclosed is a process for achieving this rough texture through a modification to the known electroless or autocatalytic techniques for coating abrasives with metals such as copper and nickel. The improvement comprises: interrupting the electroless coating process by passivating the surface one or more times; and then reactivating the passivated surface each time with a catalytic material whereby an array of preferential sites for metal deposition is obtained; and resuming normal electroless coating.
